Men can’t have children. The beginning of life requires the meeting of sperm and egg to form a fertilized egg, which will be deposited in a woman’s uterus. Men do not have a uterus, and the level of estrogenic stimulation is extremely low, so there are no basic conditions for conception of life, so men cannot give birth to children. Although men cannot have children, they need a man’s sperm to have children, so men can still pass on their genes. Men can’t have children, but the process of having children can’t be done without the participation of men. At least according to the current state of science, sperm is needed for both the natural process of pregnancy and the process of assisted reproduction. Women are responsible for most of the tasks of reproduction and need the understanding and care of society.
